Libyan Sibyl

The Libyan Sibyl was a mythological prophetic priestess from the Siwa Oasis in the Libyan desert. She was the daughter of Zeus and one of Poseidon's daughters (an immortal nymph from Crete), and the Greeks believed that she was the first woman to chant oracles. Even after her death, she continued her divinations, giving utterances in voices and omens. After Alexander the Great founded Alexandria and Egypt, he visited the Siwa Oasis, where she was said to have confirmed him as both a divine personage and as Pharaoh of Egypt.
